Interpretation
Amy (AAA-DR) started at 8:27 AM; Kien (V-DR) started at 8:47 AM. That gave Amy a 20 minutes head start on Kien. On foot, Amy ran 2:27:00 and Kien ran 2:08:05 — Kien was 18:55 faster than Amy. Amy took official place 1349th (time-based 1362nd) and Kien took official place 1351st (time-based 1326th). Amy's head start was enough to flip the official order even though Kien was faster on foot. Biggest swing: Kien gained 14:01 from Muir Woods to Cardiac.
